[Problems to be solved by the invention]
In a vehicle cabin, the air outlet is generally provided on an instrument panel, and is provided at a distal end of an air duct extending near the instrument panel. When it is desired to take a temperature-adjusted air flow from above the occupant in the vehicle interior, the air outlet is provided with a roof panel constituting a ceiling as described in Patent Document 1 described above. At the tip of an air duct extending between the air duct and the roof lining.
[0006]
For this reason, in the vehicle interior air-conditioning mechanism, in order to form an airflow from above, an air duct to be disposed on the ceiling and an air ejection port such as a register are required, resulting in an increase in the number of parts. Further, since the air duct is provided between the roof panel and the roof lining that constitute the ceiling, there is a problem that the cabin space is narrowed at least for the air duct and the head space is narrowed.
[0007]
Accordingly, it is an object of the present invention to address these problems, and to form an airflow flowing down from a ceiling by effectively utilizing a vehicle interior air-conditioning mechanism disposed on an instrument panel side in a vehicle interior. Accordingly, it is to solve the above-mentioned problems.
[0008]
[Means for Solving the Problems]
The present invention relates to a vehicle interior air conditioning mechanism. A vehicle interior air-conditioning mechanism according to the present invention is a vehicle including an air ejection port provided on an instrument panel in a vehicle interior and opening upward, and an air flow direction plate provided on a ceiling in the vehicle interior and directing an air flow. An indoor air-conditioning mechanism, wherein the air flow directing plate is provided so as to be able to protrude and retract from the ceiling at a position facing an air flow which is ejected from the air outlet and flows along the ceiling. Things.
[0009]
In the vehicle interior air-conditioning mechanism according to the present invention, it is preferable that the airflow directing plate is configured so that an occupant can perform a retracting operation on the ceiling.
[0010]
[Action and Effect of the Invention]
In the vehicle interior air-conditioning mechanism according to the present invention, the airflow ejected from the air ejection port provided in the instrument panel in the vehicle interior reaches the ceiling along the windshield, and the airflow on the front seat along the ceiling. An airflow directing plate is located in the middle of the trajectory of the airflow through the airbag and the rear seat. The airflow directing plate is provided so as to be able to protrude and retract from the ceiling, and in a state where the airflow directing plate is protruding, a part of the airflow flowing backward along the ceiling is directed downward from the ceiling. . Thereby, the occupant can take a refreshing air whose temperature has been adjusted from above, as desired, and create a comfortable atmosphere.
[0011]
If the temperature-controlled air does not need to flow from above, the airflow directing plate may be buried in the ceiling. For this reason, it is preferable that the occupant can arbitrarily perform the movement of the airflow directing plate, so that when the occupant wants the airflow whose temperature has been adjusted from above, the airflow directing plate is required each time. Can be operated so that a temperature-adjusted air flow can be taken in a timely manner.
[0012]
Thus, the vehicle interior air-conditioning mechanism according to the present invention is configured such that a part of the airflow spouting from the air outlet of the vehicle interior air-conditioning mechanism disposed on the instrument panel side in the vehicle interior is transmitted to the ceiling in the vehicle interior. Since it is directed downward by the provided air flow directing plate, an air flow outlet and an air duct for an air conditioner to be connected to the air flow outlet are extended on the ceiling of the cabin. It is not necessary to do so.
[0013]
Thus, according to the vehicle interior air-conditioning mechanism of the present invention, the air duct and the air outlet extending to the ceiling can be omitted, the number of parts can be reduced, and the air duct and air In some cases, the problem that the interior space of the vehicle is reduced due to the provision of the ejection port portion and the head space is reduced due to the reduction of the space may be solved.
[0014]
BEST MODE FOR CARRYING OUT THE INVENTION
The present invention relates to a vehicle interior air-conditioning mechanism, and FIG. 1 schematically shows a part of a vehicle interior of a vehicle equipped with a vehicle interior air-conditioning mechanism according to an embodiment of the present invention. In the vehicle interior 10, the air outlet 11 on the front side constituting the vehicle interior air-conditioning mechanism is open on the upper surface of the instrument panel 12, and is provided at the tip of the air duct facing the instrument panel 12. It is composed of provided registers. Therefore, the air outlet 11 is hereinafter referred to as a front register 11. The airflow spouting upward from the front register 11 flows rearward along the lower surface of the roof lining 13 a constituting the ceiling 13 in the vehicle interior 10.
[0015]
As shown in FIGS. 1 and 2, a predetermined width extending in the left-right direction of the vehicle compartment 10 is provided at a portion of the ceiling 13 above the front seat 14 and a portion above the rear seat 15, as shown in FIGS. Air flow directing plates 16 and 17 having a predetermined length are provided. Each of the air flow directing plates 16 and 17 is rotatably mounted at an end portion between the roof lining 13 a and the roof panel 13 b constituting the ceiling 13 so as to be vertically rotatable. 13 protrudes on a trajectory of a part of the airflow flowing along the roof lining 13a.
[0016]
Each of the air directing plates 16 and 17 is attached in a state where a predetermined sliding resistance is given, and is normally located between the roof lining 13a and the roof panel 13b in a state of being parallel to the roof lining 13a and the roof panel 13b. ing. In this state, the air directing plates 16 and 17 are buried in the ceiling 13.
[0017]
Since the air flow directing plates 16 and 17 are mounted with a predetermined sliding resistance, the occupant pulls the rear ends of the air flow directing plates 16 and 17 downward. As a result, each of the air flow directing plates 16 and 17 can be turned downward, and the downward pulling operation is released to maintain each of the air flow directing plates 16 and 17 at the turning position. be able to.
[0018]
When the occupant pushes up the rear end of each of the airflow directing plates 16 and 17 at the downward turning position, each of the airflow directing plates 16 and 17 turns upward and finally the roof. It is located between the lining 13a and the roof panel 13b and is buried in the ceiling 13.
[0019]
In the vehicle interior air-conditioning mechanism having such a configuration, the airflow spouting from the register 12 provided on the instrument panel 12 in the vehicle interior 10 reaches the lower surface of the roof lining 13 a of the ceiling 13 along the windshield 18, and , Along the lower surface of the roof lining 13a, on the front seat 14 and the rear seat 15 to the rear. In this case, the occupant can make the airflow directing plates 16 and 17 protrude halfway along the path of the airflow.
[0020]
In the vehicle interior air-conditioning mechanism, when the occupant causes the air flow directing plates 16 and 17 to protrude in the middle of the trajectory of the air flow, the air flow flowing along the lower surface of the roof lining 13a is reduced. The part is directed to the front seat 14 side and the rear seat 15 side. Thus, the occupant sitting on the front seat 14 or the rear seat 15 is exposed to the refreshed temperature-adjusted air from above, thereby creating a comfortable atmosphere.
[0021]
When it is not necessary to flow the air whose temperature has been adjusted from above, the air flow directing plates 16 and 17 may be buried in the ceiling 13. Therefore, the occupant can protrude each of the air flow directing plates 16 and 17 at a good timing to receive the air flow whose temperature has been adjusted at a good timing.
[0022]
By the way, in the vehicle interior air-conditioning mechanism, a part of the airflow blown out from the front register 11 of the vehicle interior air-conditioning mechanism disposed on the instrument panel 12 side in the vehicle interior 10 is changed to a ceiling in the vehicle interior 10. Since the air flow directing plates 16 and 17 provided in 13 are directed downward, the ceiling 13 in the passenger compartment 10 has an air flow outlet and an air flow outlet for connection to the air flow outlet. It is not necessary to extend the air duct for the air conditioner at all.
[0023]
For this reason, according to the vehicle interior air-conditioning mechanism, the air duct and the air outlet provided on the ceiling 13 can be omitted, and the number of parts can be reduced. Can be eliminated, and the problem that the head space becomes narrower due to this can be eliminated at the same time.
